Cube Palace STEP 3: Assembler (Marcille & Tanya) Walkthrough
STEP 3 Assembler boss guide: breaking Marcille & Tanya's counter-Barriers cleanly and avoiding Toughness Break stun traps.
STEP 3 Assembler (Marcille & Tanya) Clear Strategy
Clone bosses Marcille and Tanya deploy Barriers and counterattack with Basic Skills whenever hit while their Barrier survives — however, if your attack completely breaks the Barrier, NO counterattack fires! Tanya also stacks up to +60% Crit Rate, and both bosses deal heavy Toughness damage that can Break your units (disabling Trigger skills and Cross Attack while Broken).
Focus-fire Marcille and Tanya directly with Barrier-shredder Epindel: Blessing in Bloom + Bunnygirl Charlotte + Haydee + Asherah: Waltz of Starlight before their Crit stacks ramp up.
